To allwhom it may concern:

Be it known that we, WILSON T. COLE and FRANK D. HAMILTON, ofMinneapolis, county of Hennepin, State of Minnesota, have inventedcertain new and useful Improvements in Perforating or Scoring Devicesfor Printing-Presses, of which the following is aspecification.

Our invention relates to improvements in perforating or scoringattachments for printing-presses by means of which the paper may beperforated or scored simultaneously with the printing; and the objectswe have in view are to provide a device of this kind with a movableperforating or scoring bar that may be brought into position forperforating or scoring the paper just before it comes into contact withthe type, and in which the edge of the blade carrying the points orteeth for perforating or the edge for scoring is brought below thesurface of the type before the inkingrollers are passed over the face ofthe type, and in which these movements of the perforating or scoring barare accomplished by a rocking movement of the bar as distinguished froma sliding or projecting movement.

Another object of the invention is to providea device of this characterwith a solid base which may be locked into the form with the type by anydesired amount of pressure without binding the movable bar or in any wayinterfering with its operation.

Other objectsof the invention will appear from the following detaildescription, taken in connection with the accompanying drawings, inwhich- Figure 1 is a side elevation of our improved perforator or scorerwith the bar rocked into position to bring the edge of the blade belowthe surface of the type-face. Fig. 2 is a section on line a 00 ofFig. 1. Fig. 3 is aside elevation with the bar rocked into position toelevate the edge of the blade. Fig. a is a' section on line 00 00 ofFig. 3. Fig. 5 is a detail showing means for applying an extension tothe device. Fig. 6 is a detail section on line m m of Fig. 1. Fig. 7 isa section on line of x of Fig. 3. Fig. 8 is section on line a 00 of Fig.3. Fig. 9 is'an elevation looking at the end of the device and showingthe finder in its depressed position.

Fig. 10 is a view similar to Fig. 9, but showing the finder elevated.Fig. 11 is a sectional view showing .the perforator or scorer arrangedin the type-form and representing the relative positions of thetype-form and platen when the printing-press is ready for the beginningof the printing operation. Fig. 12 is a detail of the scoring-blade.

In all of the drawings, 2 represents the base of-the perforator orscorer, which consists of a solid bar having a curved recess in itsupper surface extending the length of the base. This recess forms acontinuous bearing for the rocking bar 3, which carries the perforatingor scoring blade 4. When used for perforating, this blade is providedwith the perforating teeth or points 5. When used for scoring,the bladehas a plain edge, as shown in Fig. 12. The blade 4 is preferably securedin any suitable manner in a recess in thebar 3. The bar 3-is nearlycylindrical in form, being cut away or flattened upon one side, as shownin Figs. 2 and 4 of the drawings. This bar, as already stated, isarranged in the recess in the top of the base, and the wall of therecess forms a continuous bearing for the bar.

At each end of the base a pin 7 is provided, which engages a centralsocket or recess in the end of the bar 3. These pins hold the bar inposition and form an axis or pivot upon which the bar rocks. Thepivot-pin at one end of the base is secured in a plate 8, and

this plate is provided with a lug 9, adapted to engage a socket orrecess 10 in the end of the base and to be secured in position by a pin11, which passes through the base and through a hole in the lug 9; Atthe other end of the base the pivot-pin is secured in anupwardly-extending portion of the base. At thisend of the base weprovide means for rocking the bar just prior to thetime when the paperto be printed upon is brought in contact with the face of the type.Forthis purpose we provide in the base, at this' end thereofJasocket13,'within which is arranged the vertically-sliding plunger 14,adapted to be held near the top of the socket by means of the spring 15,arranged beneath the plunger in the socket. A slot is provided at eachside of the socket. Through the outer slot 16 the lug 17, which issecured to the plunger 14.,

passes, and through the inner slot 18 a pin 19 passes, and this pinprojects between the lugs 21 and 22 on the rocking bar 3. The spring 15normally holds the plunger 14 in an elevated position, with the pin 19near the top of the slot 18, as shown in Fig. 6, and with the bar 3 inthe position shown in Figs. 1 and 6 of the drawings. The lug 17 is alsosubstantially at the top of the slot 16, as shown in Figs. 1, 9, and 10.This is the normal position of the parts,with the perforating points orteeth tn rned to one side, as shown in Fig. 6, where they are below. thesurface of the type. With the bar in this position the inking-rollersmay be passed over the face of the type without coming in contact withthe edge of the block 4, The press-platen 23 (see Fig. 11) is providedwith a suitable block 25,which may be adjusted to any desired positionthereon. This block is fixed in such position on the platen that as theplaten is moved against the type the block 25 comes in contact with thelug 17 on the perforator, moving said lug and forcing the plunger 14toward the bottom of the socket 13 against the tension of the spring 15,and thereby rocking the bar 3 from the position shown in Fig. 6 to theposition shown in Fig. 7. The bar 3 is rocked into the position shown inFig. 7 just before the platen brings the paper in contact with the faceof the type, and the lug 21 is provided with a straight surface near itsouter end, as shown in Figs. 6 and 7, so that the latter part of themovement of the plunger 14 and the pin 19 does not change the positionof the bar 3. Ve also prefer to pro vide an extension (one or more)which can be coupled to the end of said perforator or scorer for thepurpose of increasing its length. In Fig. 5 of the drawings are shown anextension base-bar 2 and an extension rocking bar 3, provided with lugsor pins adaptedto engage the sockets in the end of the main basebar androcking bar, which are engaged by lugs or pins on the plate 8 when theextension is not used. The extension base and rocking bar are providedwith similar sockets or recesses to receive the lugs or pins on theplate 8, so that when the extension is to be used the plate 8 may beremoved from the end of the main base and rocking bar and applied to theend of the extension base and rocking bar, as shown in Fig. 5.

In order to know where to set the block 25 on the platen, we provide amarker or finder on the upper part of the base 2 and at one end thereof,as shown in Figs. 9 and 10. This marker or finder consists of a pivotedlug 27, that may be turned down into the position shown in Fig.9, so asto normally stand flush with the top of the base. When the perforator orscorer has been properly placed in the type-form and the form put ontothe press, this finder is turned into the position shown in Fig.10. Theplaten,with the tympansheet thereon,is brought against the forrn'and thefinder makes an impression in the sheet, which shows Where the block 25should be located on the platen. This block may be secured on thetympan-sheet by paste or by any other suitable means.

It will be seen that our improved perforator or scorer is simple inconstruction and positive in its operation. The solid base is especiallyadvantageous, as when the device is placed in the form any amount ofpressure may be applied thereto in locking the type in the form withoutaffecting the operation of the device. The rocking bar always operatesfreely and positively, and the form of the bar and its arrangement inthe curved recess in the base provide a positive bearing for the barthroughout its entire length,which insures its always retaining itscorrect form and prevents the blade from getting out of alinement orbecoming uneven or untrue. The rocking bar may be provided either with ablade having the series of points and teeth for perforating the paper orwith the plain blade for scoring.

9 We do not limit ourselves to the details of construction, as it isobvious that many of the details may be changed or modified withoutdeparting from our invention.

Having thus described our invention, We claim as new and desire tosecure by Letters Patent 1. The combination, in a scoring or perforatingdevice for printing-presses, with the base 2 provided with a recess inits upper surface and with the socket 13 having the slots 16 and 18, ofthe plnngerltarranged in said socket, the spring 15 engagingsaidplunger, the rocking bar 3 mounted in the recess in said base, aconnection between said plunger and said bar whereby said bar is rockedas said plunger is moved, and a lug 17 connected with said plunger andpassing through said slot 16.

2. The combination, in a perforating or scoring device forprinting-presses, with the base and the movable blade, of an adjustablemarker or finder arranged upon said base, for the purpose set forth.

3. The combination, in a perforating or scoring device forprinting-presses, with the base and the rocking bar, of anextensionbase, an extension rocking bar, and means for coupling saidextension-base and extension rocking bar to the main base and mainrocking bar, respectively, substantially as described.

In testimony whereof we have hereunto set our hands this 24th day ofFebruary, 1900.
